Answer: First stage
Explanation:
The four stages of technological design include:
• identifying a problem.
• Designing a solution.
• Implement, build, and test the design.
• Determine if solution met the need.
In this scenario, Robert Shuman identified the problem. This was depicted as he stated that coal and oil would eventually run out and that humans needed to learn how to use the more-abundant energy resource of the Sun,
Answer:
Explanation:
change in the volume of the gas = 5.55 - 1.22
= 4.33 X 10⁻³ m³
external pressure ( constant ) P = 1 x 10⁵ Pa
work done on the gas
=external pressure x change in volume
= 10⁵ x 4.33 X 10⁻³
=4.33 x 10²
433 J
Using the formula
Q = ΔE + W , Q is heat added , ΔE is change in internal energy , W is work done by the gas
Given
Q = - 124 J ( heat is released so negative )
W = - 433 J . ( work done by gas is negative, because it is done on gas )
- 124 = ΔE - 433
ΔE = 433 - 124
= 309 J
There is increase of 309 J in the internal energy of the gas.
